Don't worry about it. There's no such thing as extended, primary or
logical partitions anymore in GPT, there's just "partitions".

As Pascal has said, the easiest is to create a new partition in the
free space before partition 1 (sectors 34-2047). Make sure it has the
correct type for a Bios Boot Partition (gdisk type ef02, with parted
you need to set the Bootable flag). Then reboot, as the kernel won't
load the new partition table immediately. After reboot, the
grub-install command above should work.
